About Slieve Binnian

Slieve Binnian is one of the grandest mountain venues in the Mourne Mountains, renowned for its dramatic granite tors crowning a sweeping summit ridge. The rock surface features very coarse, high-friction granite with rounded crests, deep chimney gullies, and delicate friction slabs. Facing all directions across its various tors and mountain buttresses, aspect varies, with high altitude and wind exposure driving quick drying times on exposed faces while deep gullies remain damp. The climbing is adventurous and mountain-traditional in nature, spanning Moderate scrambles to E-grade wall climbs, highlighted by Binnian North Ridge. The approach involves a sustained forty-five to sixty-minute mountain hike from the Carrick Little car park along the Mourne Wall trail. Mountain weather can deteriorate rapidly at this elevation, making full navigation equipment and warm clothing mandatory.
